Swipe (no security);

Pattern (medium security);

Some apps, like Samsung Pay or Google Pay, may also require you to set lock screen security as pattern, PIN or password.

How to customize and change app shortcuts in Galaxy S9 lock screen?

By default, there are two app shortcuts in the bottom of Galaxy S9 lock screen. The phone app is in the left side and the camera app in the right side.

When the phone is locked, the phone app allows you to make emergency calls depending on local regulations.

You can also use the camera app when Galaxy S9 is locked.

In this case, as explained in this guide, you can check photos taken in this session only. You cannot access other photos or pictures saved on the phone before you unlock the phone.

If you don’t want to have apps on the lock screen, you can disable them.
